IMPROVEMENT IN MOLE-PLOWS.

To all whom it may concern:

Be it known that I, JOHN MonRIsoN, of De Witt, in the county of De Wittand State of Illinois, have invented a new and Improved Drain or MolePlow; and I do hereby declare that the following is a full, clear, andexact description of the same, reference being had to the annexeddrawings, making a part of this specification, in which- I Figure 1 is aside view of my invention. Fig. 2 is a plan or top view of the same.Fig. 3 is a detached perspective view of the mole of the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in a novel means employed for varying theposition of the line of draft relatively with the beam and mole,substantially as hereinafter described, whereby the implement may bereadily guided or moved by the draft alone to give it the desireddirection.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents the beam of the implement, to the back part of which apendant or standard, 13, is attached, having a cutting-edge in front anda mole, O, at its lower end,which mole will be hereinafter fullydescribed.

The front end of the beam A is fitted between uprights a, that areattached to a block, D, the front part of which is rounded upward, asshown clearly in Fig. 1. The front end of the beam A is allowed to riseand fall freely between the uprights a, and it is retained at anydesired height within the scope of its movement by a screw-rod, E, whichpasses vertically through it, a proper nut being fitted in the beam forthe screw-rod to pass through. The upper part of the screw-rod passesthrough a plate, b, and is provided with a crank, c, for the purpose ofturning it and adjusting the front end of the beam higher or lower, inorder to regulate the depth of the mole C.

On the upper surface of the block 1) a horizontal bar, F, is placed andsecured at any desired point by a pin, d. At each end of the bar F thereis an eye, 6, through which a draftchain, G, passes, said chain passingalong at each side of the beam A, and having its ends attached to loopsHH, which are fitted on the ends of a traverse-bar, I, that is secured inthe back part of the beam.

Through the back part of each loop H a screw rod, J, passes, a nut beingformed on the back part of each loop, through which the screwrods pass.The screw-rods, have their bearin gs in a traverse-bar, K,which isfitted in the beam Ajust in front of the pendant or standard B.

The team or draft power is attached to the front of the chain G, and itwill be seen, by referring to Fig. 2, that the attendant by turningeither rod J niay draw back or loosen either side of the chain, andthereby change the position of the drat't-ringfeither to the right orleft, and consequently guide the plow or give it the proper direction bythe action of the draft.

The mole O is of wedge form, its sides being parallel and its top andbottom surfaces inclined, as shown clearly in Fig. 3. The standard B isattached to the mole at about the center of its length. The front edgeof the mole is slightly rounded, and both its upper and under surface,at its back part,'has a swell or rounded protuberance, g, as shownclearly in Fig. 3.

I do not claim regulating the depth of the mole G by raising andlowering the part of the beam A by means of the screwrod E, for this hasbeen previously done; but

I do claim as new and desire to secure by Letters Patent- Thedraft-chain Gr, bar F, loops H H, and the adjusting screw-rods J J, ortheir equivalents, combined, arranged, and applied to the plowsubstantially as and for the purpose set forth.

JOHN MORRISON.
